LOCKING- HANGER.

SPECIFICATION forming are of Letters Patent No. 729,440, dated May 26,1903. Application filed October 31,1902. Serial No. 129,584. (No model.)

To all whom/ it may concern:

Be it known that 1, Louis Srnrivenncnaa citizen of the United States,and a resident of the city of New York, borough of Brooklyn,

in the county of Kings and State of New York,

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi-l catecorresponding parts in both figures.

Figure 1 is a side elevation of my hanger, and Fig. 2 is a verticalsection upon the line 2 2 of Fig. 1 looking in the directionof thearrow.

The cap 1, of insulating material, is rigidly connected with a bolt 2,provided witha head 3, this head and a portion of the bolt beingpreferably embodied in the cap, as indicated The bolt 2 is furtherprovided with" Y I the bolt 2 is once set in a predetermined poin Fig.2. an enlarged threaded portion 4: and with a comparatively smallthreaded portion 5. A

metallic yoke 6 of the usual construction is 7 provided with a conicalopening 7 and is engaged by a substantially conical insulating member 8,provided with a central passage 9, whereby the same is given a somewhatannular form.

A member 10 for supporting the wire or ca ble is integrally mounted upona web portion 12, and thereby integrally connected with a socket 11,which is threaded internally and screwed upon the threaded portion 5 ofthe bolt. A lock-nut 13 is threaded internally, as shown, and screwedupon the larger threaded portion 4 of the bolt.

My invention is used as follows: The yoke 6 being mounted in the usualmanner, the bolt 2 is inserted therein from the top, the cap 1 beingcentrally disposed, as indicated in Fig. 2. The cone 8 is next fittedconcentric to the bolt and to the opening 7 of the yoke 6. The locknut13 is now passed upward over the lower end of the bolt and is screwedupon the en.- larged portion 4 thereof until the upper surface ofthe'nut is forced rigidly against the lower surface of the cone 8,thereby forcing the cap 1 and the bolt 2 downward and the cone 8 upward,.or the nut is dropped over the socket of the clip. The clip is thenscrewed fast on the lower end of the bolt, and the nut is thenscrewedtightlyon the larger threaded portion of the bolt, thereby clamping thecone, yoke, and cap firmly together. It will be observed that when theparts mentioned 1 are in the position just described a compositestructure of great strength is formed. The ear is next mounted inposition, which is done by 3 simply screwing the threaded socket 11 uponthe comparatively small threaded portion 5 at the lower end of the bolt.It will be observed thatthe screw-fastening between the socket 11' andthe threaded portion 5 of the bolt is entirely independent of thescrew-fastening between thelock-nut 13 and the larger threaded. portion.4: of the bolt; The result is that the'lock-nut 13 may be loosened ortightened at will for the purpose of adjustment or for any other purposeand that as an independ ent proposition the ear may he removed andreplaced at will. 7

By means of the device just described if sition and locked rigidly inthat position by means of the lock-nut 13 the ear when taken off andreplaced will always arrange itself in a predetermined position-say, forinstance, at right angles to the general direction of the yoke 6. Theoperative need not hesitate to take oif the ear, as the same can alwaysbe replaced so as to occupy its original position. If through any usagethe threads are worn and the ear works into a position awry, the samecan be easily corrected by loosening the lock-nut l3, adjusting the cap1 relatively to the yoke 6, and then tightening the locknut 13.

It will be observed thatv the lock-nut 13 is slightly larger than thesocket 11. This is for the purpose of enabling the lock-nut 13 to beloosened or tightened while the socket 11 is in position and withoutdisturbing the same. In other words, the lock-nut 13 can be removed fromthe threaded portion 4 and allowed to drop downward a short distance thebolt.

' ulation.

In the old style of hangers of similar construction the cap, yoke, andcone are held together by screwing the clip or ear onto the threaded endof the bolt embedded in the cap portion. 0 wing to the swaying of thetrolleypole and to many other causes the parts soon become loosened, andfinally the cap twists itself free from the threaded socket of the clip,and in consequence the line drops and interferes with the proper work ofthe current.

One object of my invention is to lock the cap, yoke, and cone firmlytogether, irrespective of the clip. In consequence the swaying of thetrolley-pole cannotloosen the hanger parts, whereby loss of time isavoided and much trouble and expense are prevented.

I do not limit myself to the particular form of device above described,as many other forms may be employed all coming Within the scope of myinvention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A hanger, comprising an insulating-cap, providedwith a depending member, a meiallic yoke engaging said cap, an earprovided with mechanism for engaging said depending member, a cone ofinsulating material for engaging said member, and a locking device forengaging said member and said cone.

2. A hanger, comprising a cap of insulating material provided with adepending member, an ear detachably connected with said de pendingmember, a metallic yoke engaging said cap, and means independent of saidear for securing said cap and said yoke rigidly together.
